f Specicationof Letters Patent. Pijgnted J 1111 Z, 1917,

Application filed November 9, 1916. Serial No. 130,362.

To all whom t may concern.:

Be it known that l, Erwin Maumee, a citizen ofhthe United States, residing at Jamaica, Long' Island, in the county of Queens and State of New York, have invented certain new and useful Improvements in Broeders, of which the following is a full, clear, and exact specification. y

This invention relates to brooders, and has for its obj ect to provide a device of this kind which is extensible and is, therefore, capable of accommodating large las well as small broods. It is the aim of this invention to provide a telescoping .brooder housing with .telescopi-ng heat conveying means, whereby the brooder may be successfully operated when contracted to its smallest size, when extended .toits largest size, and when in any intermediate adjustment. In this way provision is made for-accommodating any size of brood from that for which 7the contracted brooder is suited to that which the fully extended brooder is adapted to accommodate. Other objects will appear as the description proceeds.

The invention will be first hereinafter described in connection with the accompanying drawings which constitute part of this specication and then more specifically delined in the claims at the end of the description.

In the accompanying drawings, wherein similar reference characters are used to designate corresponding parts throughout the several views:

Figure 1 is a side elevation of a brooder constructed substantially in accordance with this invention, the same being shown fully Contracted.

Fig. 2 is a longitudinal sectional view of the brooder in its fully extended position.

Fig. 3 is a cross section on the line III-III of Fig. 2, and

Fig. a is a left hand end view of the brooder.

The casing of the brooder consists of two telescoping parts 1 and 2 having end plates 3 and 4L respectively and supported on legs 5. The part 2 of the casing lits snugly in the part 1 and is adapted to be fully telescoped into the same, as illustrated in Fig. 1. The inner end of the part 2 is supported in proper relation to the part 1 by ledges 6 formed along the bottom edges of the side walls of the part l, said part 2 having depending portions 7 at the bottom of its side i' i wall engaging' and adapted to run on said ledges. At the inner edges of the ledges G there are upwardly extending flanges 3 for positively .retaining the depending portions 7 in place on said ledges. kBoth parts 1 and 2 are equipped with curtains 9 for inclosing the space below the brooder in any adjustnient of the same.

The part l has a distributing compartment 10 for heated air adjacent to its end wall 3 and into which heated air may be supplied from any suitable source by a de-` livery pipe 11 entering said compartment l()l through an opening 12. rEhe part 2 has a similar compartment 13 for heated air adjacent its end plate t. The compartments 10 and 13 are connected by telescoping tubes of which there may be any'de'sired number. The inner section of each telescoping .tube is designated 14 and the outer section 15. Some of the inner tube sections and some of the outer tube sections, preferably an equal number of each, are mounted in each of the parts 1 and 2 of the brooder casing in order to equalize the heat in both parts when extended. A transverse partition 1G is arranged near the outer end of part 1 of the casing for holding the inner ends of the telescoping tube sections in proper position.

One or more of the larger tube sections 15 carried by the part 2 of the casing may be provided with a suitable stop 17 adapted to engage the partition 16 when said part 2 is fully extended for preventing the same from being entirely withdrawn from part 1. It will be under stood, of course, that any suitable means may be substituted for the stop 17 for accomplishing the same purpose.

The compartment 13 communicates with A a pipe 18 leading to an adjustable cap 19 by means of which the escape of the heated air, which has passed from the compartment 10 through the telescoping tube and has aocumulated in said compartment 13, may be regulated. The temperature in the casing may be automatically regulated by means of a vent 20 preferably arranged in the top of the compartment 13 and a theromstat controlled cover 21 for said vent. The thermostat 22 is also preferably arranged in the casing' and is connected to a lever 23 intermediately pivoted at 24 and connected at one end to the cover 21. The other end of the lever 23 may be connected to a damper 25 adapted to partially or fully cut 0E the pipe 11 when the cover 21 is removed from the vent 20.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:

1. In a brooder, the combination with a casing consisting of telescopmg parts, of

telescoping heat conveying tubes each com prising an inner and outer section, each part of the casing carrying an equal number of the outer and inner sections of said tube for the purpose specified.

V3. In a brooder, the combination with a casing consisting of telescoping parts, of compartments for heated air at the opposite ends of said parts, and telescoping tubes connecting said compartments. y

4. In av brooder, the combination with a casing consisting of telescoping parts, of telescoping heat conveying tubes therein, and

a partition in the outer end portion of the outer part of the casing for holding the tubes in proper position.

5. In a brooder, the combination with a casing consisting of telescoping parts, of telescoping heat conveying tubes each comprising an outer and inner section, one or more of the outer sections of the tubes being carried by the inner part of the casing, a partition in the outer end portion of the outer part of the casi-ng for holding the tubes in proper position, and a stop on one of the outer tube sections carried by theinner part of the casing, said stop being adapted to engage the partition for limiting the outward movement of the inner part of the casing.

6. In abrooder, the combination with a casing consisting of telescoping parts, Vof compartments for heated air at the opposite ends of said parts, telescoping tubes connecting said compartments, means for delivering heated air to one compartment, and means for controlling the escape of the heated air from the other compartment.

In testimony whereof I have signed my name to this specification. Y
